Thanks for the encouragement, I actually tried just that earlier today 
but I didn't have the patiance to go through all of them, now I did, the 
av710 seems to work, oddly enough there's no sound from the left front 
channel o_O But the rest seems to work. My next question then would be 
how I get Alsa to mix down and connect to the rear speaker channel 
automaticly?
